T all. whom it may concern."

Be it known that I, FRANK HELM, a citizen of the United States,`residingat Traverse Ci ty,

in the countyof Grand Traverse and State of Michigan, have invented anew and useful Machine for Making Pressed Brick, of wliichthe followingis a specification.

Aimprove the construction lof machines for The invention relates toimprovements in machines for making pressed brick.

The object of the present invention is to making pressed brick and toprovide a simple and comparatively inexpensive brick-machine of thischaracter capableof molding and conipressing clay, cement, or analogousmaterial into the desired form and adapted to produce a number of bricksat each operation of the machine.

A further object of the invention is to pro-V vide a-brick-makingmachine to whiclrthe c`ement, clay, or other material may beconveniently delivered and which aftersthe bricks have been' molded andcompressed will'enable the same to be readily removed from it.'-

Another object of the invention is to provide a brickemach'ine whichwill be adapted to ornament the bricks and which will enable the latterAto 'I be removed without injuring portion, size, and minor details ofconstruction within the scope of the claims may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of thein- In the drawings,Figure l is a side elevation, partly in section, ofya brick-machine con-1 structed in accordance with this invention, theparts being in position to support a box ofcement or other material inposition for feeding the machine'. Fig. 2 is a transverse sectional viewof the same, the verticallymovable mold-carryin g frame being depressedto carry the moldy into the cement box or re' lon the'line 5 5 of Fig;1.

A. ceptacle to fill the cells or compartments with material.- Fig. 3 isa similar view, the table being raised vfor compressing the material.Fig. 4 isa vertical longitudinal sectional View, both levers being swungupward to raise the mold 'and to lower the table or platform and lthebrick being exposed for removal from the machine'. Fig. 5 is ahorizontal sectional View Fig. 6 is a detail perspective view of one ofthe pivoted'automatically-operated supports. Fig. 7 is an enlargeddetail sectional viewof one side of the mold, illustrating theconstruction of the Lhingedgate and the' means for automaticallyopening-the saine and forlocking. the gate. Figp8 is avdetail viewillustrating the manner 'of guiding the vertically-movable cross-headwhich carries thetable or platform.

Like numerals of reference designate corresponding parts in all thefigures ofthe drawings.

1 designates a main ,frame provided with oppositely-inclined sides orstandards 2, secured to'and rising from the ends ofa base 3 andvconnected at their upper terminals bya ih'orizontal cross-piece 4.Mounted upon the main frame is a supplemental guiding-frame composed ofuprights fand a connecting top Vbar 6. The cross-piece 4 and the top bar6 are provided with registering or'alined perforations7 and 8, whichreceive parallel rods or bars 9 vof a vertically-movable frame. The barsor rods 9, which are preferably rounded, as shown, are connected attheir upper ends by a cross-head l() and at their lower ends by a moldll, thelatter being' located at a point below the top piece 4'of thebody portion of the frame of the brick-machine.

The mold l1 consists of an oblong box provided with' a series oftransverse' partitions 12, preferably constructed of metal and havingtheir lower edges 13 beveled or sharpenedto enable the partitions toreadily cut their way through a mass of ceinentfor other Inaterial, ashereinafter explained. of a width equal to the length of a brick, andthe cells or compartments formed by the partitions are of a width equalyto the thickness of a brick. The mold is provided at one side with ahinged door or section 14, provided yat The mold isv TOO its upper edgewith perforated ears 15, arranged adjacent to corresponding ears 16 ofthe mold and receiving removable pivots 17, whereby the hinged sectionor door may be readily removed when desired. The perforated ears of thehinged section or door are preferably formed by cleats or ribs, whichproject beyond the upper edge of the door or section, as shown. rl`hedoor or section may be provided, as indicated in the accompanyingdrawings, with depressions 18 to form projecting panels on the ends ofthe bricks, and corresponding panels are formed on the upper edges ofthe bricks by plungers 19, which are provided with recesses ordepressions 20.

The hinged section or door and the plungers may be provided withprojections to form depressed panels in the bricks, or any other desiredornamentation may be provided. rlhe hinged section or door and theplungers may be constructed to form a rock-face on the front ends andupper edges of the bricks, and after the bricks have been compressed, ashereinafter explained, the hinged section or door is released and isautomatically swung outward or open by a spring 21, arranged in 'anupright position at the front of the mold and secured at its upper endto the same and having its lower end engaging an eye 22 of the hingedsection or door. The ends of the mold 'are provided with projecting arms23, having bearings for the reception of journals 24 of a cam 25. Thecam 25, which is provided with a central handle or operating-arm 26, isarranged to engage cleats 27 of the door or section of the mold. Whenthe operating arm or handle 26 is swung downward, the cam is carriedinto engagement with the hinged door or section, andthe latter is heldfirmly closed while the bricksare being molded. When it is desired torelease the bricks, the operating arm or handle is swung upward and thespring automatically throws the hinged door or section outward beyondthe ornamented end faces of the bricks, thereby permitting the mold tobe raised from the bricks without marring or otherwise injuring the saidornamented end faces.

The plungers 19, which are stationary, are vertical and are secured attheir upper ends to the top cross-piece 4 of the main frame of themachine and are provided at their lower ends with suitable heads 29,which correspond in shape and size to the cells or compartments of themold. These plungers, which are stationary with relation to the mold andto a lower vertically-movable cross-head 30, are preferably secured tothe top of the main frame Vof the brick-machine by means of a detachableplate or board 31, whereby the plungers are adapted to be removed forenabling another set of plungers having a different design to be appliedto the brick-machine.

The vertically-movable cross-head 30, which is provided at its ends withV-shaped notches 32 and 33, is engaged by guides 34 and 35 of triangularshape secured to the inner inclined faces of the ends 2 of the mainframe and provided with vertical guiding edges, which are oppositelybeveled to conform to the configuration of the notches 32 and 3i) of thelower vertically-movable crosshead. ',lhe lower face of the cross-head30 and the upper face of the base 3 of the main frame are provided withbearing-recesses 3G and 37, detachably receiving toggle-levers 38,arranged in pairs, as clearly shown in Figs. l and 2. The members ofeach pair are connected by a horizontal pivot, and the latter areconnected by a link 39. One of the pivots of the toggle-levers isconnected by a link or bar-1 0 with a lower operating-lever 41, havingone end 42 bifurcated and fulcrumcd on one end of the main frame of thebrick-machine near the bottom thereof between suitable bearings 43. Theend or standard upon which the lever 42 is fulcrumed is provided with aslot or opening to receive the connecting bar or link 40, which ispivoted at its outer end by a pin 44 or other suitable fastening devicein the bifurcation of the lower operating-lever. The togglesleverspreferably consist of two sides and an intermediate connecting portion,as clearly shown in Fig. 2, and the inner end of the connecting bar orlink 40 is enlarged and extends across thespace between the sides oftheadjacent toggle-levers. lVlicn the lower operating-lever 41 is swungdownward from the position illustrated in Fig. 1 of the drawings, thetoggle-levers will be straightened and'the lower vertically-movablecross-hezul 30 will be elevated, and when the lower level' 4l is swungupward the lower cross-head will be moved downward.

The lower cross-head is provided with a table or platform 45, and it hasmounted upon it pivoted supports 46, located at the ends of the table orplatform, which extends longitudinally of the cross-head 30. The pivotedsupports are composed of two sides and a counecting portion providedwith an upwardlyextending inclined arm 47. The sides are enlarged attheir lower ends to forni feet and are pivoted at the outer portionsthereof to transverse cleats 48 by pins 49 or other suitable fasteningdevices. '.l`he upper ends of the sides form shoulders 50,`arranged tosupport a box 51, which is adapted to contain the cement, clay, or othermaterial from which the bricks are molded. The box, which is open at thebottom, has inwardly-exteiuling bottom flanges 52, provided with concaveupper faces forming projecting edges 5?, which are adapted to litagainst the lower face of a removable bottom board 54, whereby a tightjoint is effected. The box with its removable bottom in position in thebottom flanges is iilled with cementor other material, which is scrapedofi' level with the upper edges of the box, and the latter is thenplaced IOO llO

upon the supports 46 in the position. illustrated in Fig. l of theaccompanying draw- The opening within the bottom Iianges of theboxcorrcsponds in size to the `table or platform which projects into theopening, as shown. rIhe mold is then moved downward to the positionindicated in Fig. 2 of the drawings by means of'an upper operating-lever55. bifurcatedto straddle the upper supplemental `or guide frame andfulcrumed at its inner end on the same at one side thereof..l

- The other end of the lever 55 is shaped intoa handle, and the sidesformed by the bifurcation are connected with the top cross head or piecel() by links 56. Instead, however, of employing operating-levers foractuating the vertically-movable frame and the lower vertically-movablecross-head any other suitable means may be employed, and a suitablemotive power may be provided foractuating these parts.

The downward movement of the moldwithin the box or receptaclesuppliesthe brick cells or compartments with concrete or other material, and thelower cross-head is then raised by swlnglng the lower operating-leverdownward. The upward movement of the lower cross-head carries thematerial against the stationary pluugers, and the bricks are molded andfirmly compressed. This upward movementalso carries the inclined arms 47of the pivoted supports into engagement with approximately L-shapedtrips 57, .fixed to the inner faces of the sides or standards 2 andarranged in the path of the saidv arms 47. The supports are drawnoutward by the trips, and
